You don't use flops because you rarely put yourself in a position to have to use one LOL
I use all the arsenal I'm given and regularly. I prefer pitching as the ball goes straight at the flag. A flop you have to move the marker to achieve a straight shot. so I can't see that a flop is easier to judge.
I only use the flop when I need to get it up and down in a hurry.
On the question of moving the ding point, I can't see that would make any difference to the judgement of the shot. Unless of course you were hitting it 100% all the time. Unless of course you are using a sticky percentage graph and that would then change the power of your hit.
My two bobs worth.
